Find has an extremely expressive command line for selecting specific files that are of interest to you. These will then be recursively uploaded into Galaxy, maintaining the folder hierarchy, a useful feature when moving legacy data into Galaxy. For a complete description of the options of this script, you can run python$GALAXY_ROOT/scripts/api/library_upload_dir.py--help

This tool will not overwrite or re-upload already uploaded datasets. As a result, one can imagine running this on a cron job to keep an “incoming sequencing data” directory synced with a data library.
